By this spell, you may open a doorway directly into the aethyr, allowing two-
way exchange between the world of potential and the physical realm.
You may use the gate to call forth spirits, to seek out a target and affect it with
magical words and gestures, to seek out hidden information, or to gain
access to a particular sort of energy which you may then apply toward
other spells.
Begin by defining the area in which the Gate will open with the
use of a boundary surrounded by signs appropriate to the nature of the
gate.
If it is to be in some vessel (such as a pit or cauldron), mark the
boundary signs around the edge. If it is to be on the ground, draw an
appropriate closed polygon. If it is to be in the air, define its boundaries with
signs drawn in the air.
This done, "stir" the interior of the gate so as to
confound the attention and prevent interfering thoughts. Focusing on the
center of the gate, speak a magical word which opens the portal to other
worlds.
Due to the uncertain nature and contents of these worlds, it is wise
to employ a Protection spell in conjunction with the making of a gate.
